Testing and measurement of friction, wear, and material mechanical properties Tribometers and Mechanical Testers Research into materials and how materials can be changed to influence strength, integrity, or durability is an integral part of product design and improvement across nearly every industry. In brief, an in-house-built tribometer was used and operated in ball-on-flat linear reciprocating test conditions with a stroke of ~1 mm at a reversing frequency of ~1 Hz. Plane polished titanium alloy (Ti6Al4V) samples were used along with 10 mm diameter counterbodies (hardened 100Cr6 steel or Si 3 N 4 ceramic) in dry or oil-lubricated .Bruker’s High Frequency Reciprocating Rig (HFRR) Module for the UMT TriboLab™ Mechanical Tester enables a versatile and cost-effective way to screen lubricants and materials at the benchtop scale. Traditionally, the testing of surfaces and lubricants on reciprocating systems, such as engines and linear compressors, has required the use of laboratory-scale tribometers .Try high speed reciprocating friction and wear tester MDW-02 - jinanyihua Products Made In China, China Manufacturer. 1. Description High-speed reciprocating friction and wear testing machine is mainly used for testing the friction and wear performance of materials and surface coatings. The machine adopts weight to load 50g -- 2000g; Automatic constant loading; .
The Triboster TSf-503 is designed for computer-controlled analysis of the static and kinetic coefficient of friction (COF). The highly versatile device, with its linear reciprocating sample stage, can be used for all kinds of samples with different shapes because fixtures can be specially designed according to the sample. The rig used is a slightly modified version of the one developed for unidirectional sliding by the present authors in Bin Jaber et al. [36].The approach is somewhat similar to the sled-type friction test in ASTM D1894 [37].A schematic representation of the rig is shown in Fig. 2 (with numbers indicating the key components). The contact adopted for the study was a flat .It supplies several tribological and mechanical testing solutions for various industries. Today, the MFT-5000 is widely used to measure the friction coefficient for lubricants and grease. Testing applications also include bio, automobile, semiconductor, aerospace, .The requirement was to develop a test methodology that would quickly deliver differentiable and reproducible friction and wear results. Oscillation was chosen as the test motion, which, in combination with the test force, ensures the most .
Linear wear friction test reproduces the linear reciprocating motion found in many real-world tribology mechanisms. A flat, pin or ball tip is loaded onto a test sample with a precise weight. The test samples can be of varied shape (such as cylindrical) as long as there is a flat zone of a certain length in the direction of movement.

2.1 Pin-on-Disk Tribometer. The most commonly used configuration for testing materials is the pin-on-disk method in either rotating or linear-reciprocating modes. The corresponding ASTM standards, G99 [] and G133 [], include the measurement of friction coefficient as well as wear rate of the sample and the static partner.The pin-on-disk setup has .
The vertical load, friction ball diameter and reciprocating movement frequency (friction speed) are selected as the experiment factors. The cutting tools was installed in the special designed fixture on a reciprocating movement wear test machine. The wear depth increases with the increase in the Z-load, ball diameter and frequency. Molybdenum disulphide (MoS2) based solid lubricant mixtures containing zirconia and graphite were prepared in the laboratory and coated on steel specimens. The experiments were done using reciprocating scratch test for various numbers of cycles. The results showed that the addition of zirconia and graphite into the MoS2 lubricant has improved its properties in .2.Set the test parameter: Stroke length, reciprocating frequency, friction, test temperature and test time. It also can do the course setting to each parameter. 3.Control the mechanical part running time, it can keep monitoring the stroke length, reciprocating frequency and sample temperature. When the temperature is at the set value, the test .
The friction and wear properties of piston and sleeve pairs of different materials in a metal sealing device were simulated by the laboratory “pin-on-block” reciprocating friction test. Pins made of 45# steel, 35CrMo, and 20Cr13 were used to simulate piston bulges, while 35CrMo samples were used to simulate sleeves.
